The term "metaverse" refers to a collective virtual shared space, created by the convergence of virtually enhanced physical reality and physically persistent virtual space, including the sum of all virtual worlds, augmented reality, and the internet. In the context of blockchain, the term "metaverse" is often used to describe virtual worlds that are built on top of decentralized networks, and which use blockchain technology to store data and facilitate transactions. The goal of many metaverse projects is to create immersive, interactive virtual environments that can be accessed and experienced by users from anywhere in the world. These virtual environments can be used for a variety of purposes, such as gaming, socializing, education, and more. Some popular examples of metaverse development projects that use blockchain technology include Decentraland, Cryptovoxels, and Somnium Space.
